I tried both tfm and unicode-math now. Both do not show any effect of 
subdepth. However, with tfm the subscript behaves as described in the 
TeXbook – with unicode-math (and thus lm-math.otf), it even has the 
inverse effect: If a superscript is present, the subscript is *raised*. 
I never noticed that one before …
I'll write this to the LuaTeX list because at least the latter one seems 
to be clear bug to me?

Best, Arno
